Based on historical weather data for December, the expected race day conditions are as follows. Cold conditions are expected, with temperatures between -3°C and 8°C.

Rocket City Marathon is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are usually slower than the road equivalent - often by 10-20% - because of uneven footing, technical sections, and frequently steeper gradients, though a smooth, non-technical or downhill trail can run faster than that suggests. Trail-specific shoes with good grip are recommended.
